HYD RANT.

SPECIFICATION forming part of Letters Patent No. 400,414, dated March 26, 1889.

Application filed September 24,1887. Serial No. 250,541. (No model.)

To all whom it may concern;

Be it known that 1, WILLIAM RYLE, a citizen of the United States, residing at Paterson, Passaic county, State of New Jersey, have invented anew and useful Improvement in Hydrants, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in hydrants.

It has been customary usually to use iron exclusively for caps for the discharge piece or nozzle in hydrants. Caps thus made exclusively of iron are found to be objectionable, for the reason that the screw-thread cut in the inner rim surface of the iron cap soon corrodes and becomes rough, in which condition the rough corroded wasting-thread of the cap, in the oft-repeated operation of being screwed on or off from the brass discharge piece or nozzle of the hydrant, subjects the latter to excessive wear, making frequent renewals of the engaging parts necessary.

The object of my present invention is to provide a cap for the discharge piece or nozzle in hydrants which shall possess the advantages of the cap made exclusively of iron, but which shall be free from its objectionable features.

With this end in view my invention consists in the novel arrangement of a brass threaded bushin an iron cap-frame; and my invention further consists in certain features of construction and combination of parts, as will be hereinafter fully described, and pointed out in the claim.

Figure 1 of the drawings shows my improved hydrant-cap in section. Fig. 2 shows in section a part plan of the same, taken on line a: as of Fig. 1; and Fig. 3 is a vertical sectional elevation of a hydrant having my improved cap in position thereon.

A represents an improved nozzle-cap for hydrants, in the iron frame, B, of which cap I arrange and fix a brass bush, C.

The bush, which is made larger in diameter at the top than at the bottom of the same,

I provide with a series of recesses, D. These recesses are arranged in the outer form of the bush, and which, when the frame is cast around the. bush in the mold, cause protuberances to form on the inner frame surface and in the recesses D, by means of which protuberances the bush is held fixed circumferentially, while the battering form of the bush holds the same fast vertically when the metal in the cast closes around the same.

The bush 0, which is held from turning in the frame B by the protuberances formed on the frame and in the recesses, and held fixed in vertical position by its battering form, is provided with a screw-thread, E, and is adapted to screw on a corresponding screw-thread arranged therefor on the nozzle of the hydrant.

It will be seen that the cap A is composed mainly of cast-iron, and retains mostly its former cheapness, While by means of the bush-threaded portion 0 brass meets brass, by the non-corrosive quality of which the engaging parts of the cap and nozzle will last indefinitely.

The bush 0 may be made of any other noncorrosive material than brass that is adapted to such use, and may be made in any suitable form, and be fastened in position by rivets or otherwise than by being cast in, without changing the nature of my invention.

I am aware that cast-iron and brass or other non-corrosive materials have been used for closing hand-holes in soil, waste, or drain pipes, traps, &c., as shown in Patent No. 336,476, dated February 16, 1886; but my invention does not include any device appertaining to soil, waste, or drain pipes, traps, &c., nor do I claim any device appertaining thereto.

Having described my invention ,what I claim is- A hydrant-nozzle cap consisting of an internally-screw-threaded brass bush open at each end and having one end of larger exterior diameter than the other end, and provided with a series of recesses, D, extending lengthwise in the tapering outer surfaceof the bush, substantially parallel with the internal screw-thread, in combination with an outer frame of iron cast about the said bush, closing the opening at the larger end of it and engaging with the said recesses, substantially as and for the purpose set forth.
